Portland police Sergeant Martin Flannery said specialist units and uniform members executed search warrants at properties in Portland's Wellington Road and Patrick Street in the early hours of Wednesday morning.

Police allegedly forced their way into the Wellington Road house after the occupants failed to open the door.

A search of the premises revealed three syringes loaded with methylamphetamine and blood, three green lasers, quantities of a white crystal substance believed to be ice and two white iPhones containing significant drug trafficking conversations.

Police also located inside a vehicle several ziplock bags containing ice, 16 grams of cannabis on top of a child's baby seat, three digital scales, 6.5 grams of heroin, used needles and $350 cash believed to be the proceeds of crime.

A total of 6.96 grams of ice was found inside the house and vehicle.

Sergeant Flannery said a young child was present at the time of the raid. He said the child's mother and a man were arrested at the scene.

"This is a real concern for us, the exposure of young children to that sort of lifestyle is very alarming," he said.

Andrew Ryan, 31, and Bronwyn Noku, 35, of Wellington Road, appeared in Warrnambool Magistrates Court on Thursday.

Mr Ryan made no application for bail and was remanded in custody until June 17.

Court documents obtained by The Standard revealed Ms Noku had admitted to buying 3.5 grams of ice to sell weekly. She told police she sold one point of ice for $50.

Magistrate Franz Holzer said Ms Noku had failed to show compelling reasons why she should be released and remanded her in custody. She will appear in court the same day as Mr Ryan.

Sergeant Flannery said the Wellington Street property had been an address of interest for some time.

"Action was taken on Wednesday as a result of information received from the community, which added to our significant amount of intelligence suggesting there was a high level of drug trafficking occurring at that house," he said.

"This is an example of the public's good work in assisting us to remove this sort of offending from our town. Getting these drugs off the streets reduced the harm on the community.

"This has been an ongoing investigation conducted by the Southern Grampians divisional tasking team, with the warrants executed with the assistance of Portland and Hamilton crime investigation units and Portland uniform members. It has been a really positive, team effort.

"The Southern Grampians divisional tasking team has a strong focus on minimising the harm of drugs in the community. We will act on any information and use the full extent of the law deal with it.

"Anyone with information should contact Crime Stoppers or myself, Brenton Erkens-Goss and Victoria Hudson at Portland police station."
